This beautiful avocado stone art is mind-blowingly intricate

If you think about how many avocados the average household consumes, that's an awful lot of stones being chucked away.

But one artist saw treasure where the rest of us saw trash and began to carve intricate figures into the stone, Metro.co.uk reports.

'I started my unusual hobby in 2014. I was making my lunch and opened a perfectly ripe avocado as a special treat. It struck me that the stone I found inside the avocado was a particularly beautiful one,' artist Jen Campbell explains on her website Avocado Stone Faces. 'It felt like a shame to just throw it into the compost.'

So instead she gathered together the craft tools she had at home and started to carve the smooth surface of the stone into a 3D image. From then on she was 'hooked' and headed straight to her local supermarket to stock up on avocados.

' I decided to make an Instagram account devoted entirely to my new hobby, where I could essentially keep a photo diary of my carving progress,' and so Avocado Stone Faces began.
